How do I decode this?

My university offers some classes online and to access any lecture you only need a valid log in and knowledge of the url.

They use this scheme:

http://www.XXXXXX.edu/mediaportal/flvplayer.aspx?FileID=eaa343c9-218a-41dc-86e6-a

The only thing that changes is that hexadecimal string.

I thought they might be uploading the lectures and sequentially naming them in base 16. Now I'm getting the feeling that they assign a random number in base 16 to each lecture as a means of preventing people from poking around and landing on a sequence of lectures by chance.

I was going to convert each section to decimal and see if I can identify a pattern, but decided to drop in here and see if I can get any useful input.
